Survival benefit from immunocheckpoint inhibitors in stage IV non-small cell lung cancer patients with brain metastases: A National Cancer Database propensity-matched analysis.

ABSTRACT: Immunocheckpoint inhibitors (ICIs) have become a standard pharmacological therapy in non-small cell lung cancer (NSCLC). Because brain metastases (BMs) have historically been listed as exclusion criteria in previous clinical trials involving ICIs in advanced NSCLC, the survival benefit from ICI in NSCLC patients with BMs remains unclear. The National Cancer Database was queried for stage IV NSCLC patients with or without BMs between 2014 and 2015. Overall survival (OS) of stage IV NSCLC patients who received immunotherapy and that of stage IV NSCLC patients who did not receive immunotherapy were compared according to the presence or absence of BMs. Multivariable logistic analyses identified the clinical characteristics predictive of overall survival. A propensity score analysis was conducted with the aim of adjusting the potential biases arising from the clinical characteristics. This study included 42,512 patients with stage IV NSCLC; 11,810 patients with BMs and 30,702 patients without BMs. In univariate analysis, stage IV NSCLC patients with BMs treated with immunotherapy had a significantly longer OS than those without immunotherapy after propensity score matching (median OS: 12.8 vs 10.1 months, hazard ratio [HR]: 0.80, 95% confidence interval [CI]: 0.72-0.89, p < 0.0001). Multivariable Cox modeling after propensity score matching confirmed the survival benefit from ICI for stage IV NSCLC patients with BMs (HR: 0.75, 95% CI: 0.67-0.83, p < 0.0001). The HR in NSCLC patients without BMs treated with ICI compared with those without ICI was 0.77 (95% CI: 0.73-0.82, p < 0.0001). Survival in stage IV NSCLC patients with BMs was significantly improved by ICI treatment at levels comparable to those without BMs using a retrospective database. ICI may be one of the promising treatment options for stage IV NSCLC patients with BMs. These findings should be validated in future prospective studies.

Project description:BackgroundOpioid dependence is a public health crisis and surgery is a risk factor for long-term opioid use. Though minimally invasive surgery (MIS) is associated with less perioperative pain, demonstrating an association with less long-term opioid use would be another reason to justify adoption of minimally invasive techniques. We compared the rates for long-term opioid prescriptions among patients in a large national database who underwent minimally invasive and open colectomy.MethodsUsing the MarketScan Database, we retrospectively analyzed patients undergoing colon resection for benign and malignant diseases between 2013 and 2017. Among opioid-naïve patients who had ≥ 1 opioid prescriptions filled perioperatively (30 days before surgery to 14 days after discharge), propensity score matching was applied for group comparisons [open (OS) versus MIS, and laparoscopic (LS) versus robotic-assisted surgery (RS)]. The primary outcome was long-term opioid use defined as the proportion of patients with ≥ 1 long-term opioid prescriptions filled 90-180 days after discharge. Risks factors for long-term opioid use were assessed using logistic regression.ResultsAmong the 5413 matched pairs in the MIS versus OS cohorts, MIS significantly reduced long-term opioid use of 'any opioids' (13.3% vs. 20.9%), schedule II/III opioids (11.7% vs. 19.2%), and high-dose opioids (4.3% vs. 7.7%; all p < 0.001). Among the 1195 matched pairs in the RS versus LS cohorts, RS was associated with less high-dose opioids (2.1% vs. 3.8%, p = 0.015) 90-180 days after discharge. Other risk factors for long-term opioid use included younger age, benign indications, tobacco use, mental health conditions, and > 6 Charlson comorbidities.ConclusionMinimally invasive colectomy is associated with a significant reduction in long-term opioid use when compared to OS. Robotic-assisted colectomy was associated with less high-dose opioids compared to LS. Increasing adoption of minimally invasive surgery for colectomy and including RS, where appropriate, may decrease long-term opioid use.
